COLLAPSIBLE BOX WITH SIDE WALL ARTICLE SUPPORTS
A parallelogram shaped box with side walls formed by parallel, generally rectangular bar members has a plurality of grommets inserted into the side walls between the bar members. Each grommet is trapped between adjacent bar members by clamping of adjacent bar members. Each grommet has a thickness greater than the thickness of the bar members and has a boss in the grommet with a pin retainer in the grommet, such as a straight hole. A pin placed in the pin retainer can support a decorative article so that external sides of the box can be decorated.
This application claims priority from provisional application Ser. No. 62/106,930 filed Jan. 23, 2015.
TECHNICAL FIELDThe invention relates to receptacles and, more particularly, to receptacles with side wall article supports.
BACKGROUND ARTIn U.S. Pat. No. 4,664,282 to Michael and David Chan disclosed a collapsible plant holding structure made of rectilinear bar members that were hinged at each end using a pole that runs through ends of the bar members. The bar members are stacked so that there are spaces between parallel members in each direction with one bar being offset from a counterpart extending at right angles. The bars are stacked in four directions to define a rectangle or parallelogram. The disclosure of U.S. Pat. No. 4,664,282 is incorporated by reference herein and the article of manufacture disclosed therein is referred to as a Chan Box.
SUMMARY OF INVENTIONWhile the Chan Box of the prior art is useful for supporting plant pots and the like within the box, an object of the invention was to add decorative members to side walls external to the box without impairing the integrity of the box.
The above object has been met by modifying the Chan Box in a manner such that parallel rectangular bar members that form side wall panels trap grommets that span the thickness of the bar members. The grommets have a boss therein that projects outwardly beyond a plane of the panel. The boss has an aperture therein that serves as a pin retainer, the aperture generally in a parallel plane to the parallel bar members. A pin inserted into the pin retainer may have an upright decorative article which, if planar, is parallel to a side wall panel. In this manner, the integrity of side wall members is not affected.
With reference to
Each horizontal bar member has a horizontal thickness which is a substantial fraction of the vertical height of a bar. For example, if a bar is 1 centimeter in height, the bar is at least one-half centimeter in thickness depth. The depth of the bars is used to trap grommets 16 and 18, each of which has a depth that slightly exceeds the depth of a horizontal bar. The grommets are trapped between adjacent bars.
Atop of each grommet are spaced apart ridges which engage edges of a bar. The spaced apart edges are like small rails that prevent the grommet from moving in or out of the box 10 once the grommet is seated in place. The grommets are seated in place by loosening a post 14 so that the bar members can be slightly moved up to allow insertion of the grommet and when moved down the post can be fastened in place, for example by screw threads at the end of the post that threads into a nut.
In
With reference to
Upward stacking of boxes allows for decorative arrangements of flower pots and the like while the outwardly extending grommets provide opportunities for mounting jewelry, sculptures or other decorative structures.
Claims
1. A collapsible box with side wall article supports comprising:
- an arrangement of four panels arranged in a parallelogram configuration, each panel having a plurality of parallel, generally rectangular bar members having opposite ends with holes therein, supported at each end by upright posts extending through holes of stacked bar members, the rectangular bar members having a characteristic bar thickness, and
- a plurality of grommets fitting tightly between adjacent parallel bar members, each grommet having a boss with a pin retainer therein, the grommet having a grommet thickness corresponding at least to the bar thickness that provides linear support for a pin retained in the boss.
2. The apparatus of claim 1 wherein a pin has a decorative member at one end thereof, the pin having an opposed end extending into a boss through the pin retainer.
3. The apparatus of claim 1 wherein the pin retainer is a straight hole through the grommet.
4. The apparatus of claim 1 wherein each grommet has two parallel opposed sides, with each side having edgewise parallel rails that engage the bar members at opposed ends of the characteristic bar thickness.
5. The apparatus of claim 1 wherein each boss extends outwardly beyond parallel side rails of a panel.
